Localisation of MAO-A and -B in human lung and spleen was studied by immunohistochemistry. The primary antibodies used were mouse monoclonal anti-human MAO-A (6G11/E1) and anti-human MAO-B (3F12/G10/2E3). Samples of lung and spleen were obtained from 6 routine autopsy cases. Both immunoreactivities showed a homogeneous distribution in lung, where all cell types had both MAO-A and -B staining. In spleen MAO-A and -B showed a very weak immunoreactivity, which was restricted to smooth muscle cells and reticular cells of the white pulp. These data represent the most comprehensive study of MAO-A and -B localisation in the two tissues.
